Edit report at https://bugs.php.net/bug.php?id=75373&edit=1 ID: 75373 Comment by: tm8544 at hotmail dot com Reported by: tm8544 at hotmail dot com Summary: Warning Internal error: wrong size calculation Status: Open Type: Bug Package: opcache Operating System: Windows 10 x64 PHP Version: 7.2.0RC4 Block user comment: N Private report: N New Comment: The first comment led me thinking that after all, what if it is about an already cached script? I my PHP.ini some opcache config options were commented out, so they were in their default values. I changed this so that I specifically gave those options the default value. For opcache.file_cache_consistency_checks I also changed the value, even though file_cache is not used. Here are all config options, changed lines are marked with ***, left is the new value / right is the old value. opcache.enable=1 / opcache.enable=1 opcache.enable_cli=0 / opcache.enable_cli=0 opcache.memory_consumption=128 / opcache.memory_consumption=128 opcache.interned_strings_buffer=8 / opcache.interned_strings_buffer=8 opcache.max_accelerated_files=4000 / opcache.max_accelerated_files=4000 *** opcache.max_wasted_percentage=5 / ;opcache.max_wasted_percentage=5 *** opcache.use_cwd=1 / ;opcache.use_cwd=1 opcache.validate_timestamps=1 / opcache.validate_timestamps=1 opcache.revalidate_freq=60 / opcache.revalidate_freq=60 opcache.file_update_protection=3600 / opcache.file_update_protection=3600 opcache.revalidate_path=1 / opcache.revalidate_path=1 opcache.save_comments=1 / opcache.save_comments=1 opcache.load_comments=1 / opcache.load_comments=1 opcache.fast_shutdown=0 / opcache.fast_shutdown=0 *** opcache.enable_file_override=0 / ;opcache.enable_file_override=0 opcache.optimization_level=0xffffffff / opcache.optimization_level=0xffffffff *** opcache.inherited_hack=1 / ;opcache.inherited_hack=1 *** opcache.dups_fix=0 / ;opcache.dups_fix=0 opcache.blacklist_filename=c:\PHP\php.ini.opcache_blacklist.txt / opcache.blacklist_filename=c:\PHP\php.ini.opcache_blacklist.txt *** opcache.max_file_size=0 / ;opcache.max_file_size=0 *** opcache.consistency_checks=0 / ;opcache.consistency_checks=0 opcache.force_restart_timeout=15 / opcache.force_restart_timeout=15 *** opcache.error_log="" / ;opcache.error_log= opcache.log_verbosity_level=2 / opcache.log_verbosity_level=2 *** opcache.preferred_memory_model="" / ;opcache.preferred_memory_model= *** opcache.protect_memory=0 / opcache.protect_memory=0 *** opcache.restrict_api="" / ;opcache.restrict_api= opcache.mmap_base=0x20000000 / opcache.mmap_base=0x20000000 *** opcache.file_cache="" / ;opcache.file_cache= *** opcache.file_cache_only=0 / ;opcache.file_cache_only=0 *** opcache.file_cache_consistency_checks=0 / ;opcache.file_cache_consistency_checks=1 *** opcache.file_cache_fallback=0 / ;opcache.file_cache_fallback=1 *** opcache.huge_code_pages=0 / ;opcache.huge_code_pages=1 *** opcache.validate_permission=0 / ;opcache.validate_permission=0 *** opcache.validate_root=0 / ;opcache.validate_root=0 After this, I have not seen any warning of wrong size calculation in Apache log. Could it be that PHP7.2.0 handles opcache config option default values differently than e.g. 7.1 or previous versions?

It happens even when the server is restarted, so there should be no cached scripts in memory. It is always those three scripts, values for 'start', 'end' and 'real' change from time to time ------------------------------------------------------------------------ [2017-10-13 18:14:19] spam2 at rhsoft dot net I faced this "internal size error" randomly after upgrade to php 7.1.x in production but can't trigger it reliable - when it happens it is always after replace a already cached script ------------------------------------------------------------------------ [2017-10-13 17:37:51] tm8544 at hotmail dot com Description: ------------ 7.2.0RC4 and also 7.2.0RC3 caused following lines in Apache error.log after server or Apache service (re)start. In this case, on Thursday evening after updating to 7.2.0RC4 + Apache restart, and on Friday Morning after scheduled server restart.
